In the spirit of what, exactly? The name was inspired by her book, In the Spirit of the Hamptons, about the famous chichi playground for the elite. But, says Bensimon, the scent "should always be in the spirit of you."

The 45-year-old New Yorker became obsessed with perfumes as a model in Paris, where she fell in love with the city's floral shops and the arrangements she'd see in the ateliers of Karl Lagerfeld, Valentino, and other designers. When she met scent guru Sarah Horowitz, the two decided to collaborate. After just minutes of mixing and matching scents, In the spirit of was created.

According to a press release, Bensimon's scent "has a sparkling top note of fresh cut lemon. The middle note accord is honeysuckle meeting with the lush, tropical note of tuberose, accented by a touch of spicy carnation. It rests on a base note accord of clean musk with a hint of the sexiest vanilla that is at once beautiful, warm and deep — just like the woman who inspired it."

Bensimon spoke to Us about her favorite celebrity fragrances on Oct. 3 at a screening of The Inevitable Defeat of Mister and Pete hosted by The Cinema Society and Tommy Hilfiger in NYC. "I like Kim Kardashian — it's a well done fragrance. Justin Bieber — I don't know what the base is, but it smells really good and my kids love it too. I really like the Britney Spears since it smells like carnations."
